Summaries for CYP1A2 Gene

Entrez Gene Summary for CYP1A2 Gene

  • This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. The protein encoded by this gene localizes to the endoplasmic reticulum and its expression is induced by some polycyclic aromatic hydrocarbons (PAHs), some of which are found in cigarette smoke. The enzyme's endogenous substrate is unknown; however, it is able to metabolize some PAHs to carcinogenic intermediates. Other xenobiotic substrates for this enzyme include caffeine, aflatoxin B1, and acetaminophen. The transcript from this gene contains four Alu sequences flanked by direct repeats in the 3' untranslated region. [provided by RefSeq, Jul 2008]

GeneCards Summary for CYP1A2 Gene

CYP1A2 (Cytochrome P450 Family 1 Subfamily A Member 2) is a Protein Coding gene. Diseases associated with CYP1A2 include Toxicity Or Absent Response To Clozapine and Acetaminophen Metabolism. Among its related pathways are Gefitinib Pathway, Pharmacokinetics and Estrogen Receptor Pathway. Gene Ontology (GO) annotations related to this gene include enzyme binding and iron ion binding. An important paralog of this gene is CYP1A1.

UniProtKB/Swiss-Prot for CYP1A2 Gene

  • Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Most active in catalyzing 2-hydroxylation. Caffeine is metabolized primarily by cytochrome CYP1A2 in the liver through an initial N3-demethylation. Also acts in the metabolism of aflatoxin B1 and acetaminophen. Participates in the bioactivation of carcinogenic aromatic and heterocyclic amines. Catalizes the N-hydroxylation of heterocyclic amines and the O-deethylation of phenacetin.

Polymorphic Variants from UniProtKB/Swiss-Prot for CYP1A2 Gene

CP1A2_HUMAN-P05177
The CYP1A2*1F allele which is quite common (40 to 50%) is due to a substitution of a base in the non-coding region of the CYP1A2 gene and has the effect of decreasing the enzyme inducibility. Individuals who are homozygous for the CYP1A2*1F allele are slow caffeine metabolizers. Thus for these individual increased intake of caffeine seems to be associated with a concomitant increase in the risk of non-fatal myocardial infraction (MI).
